SLIDING-WINDOW' HOLDER.

Application led October 11, 1926, Serial No. 140,766. Renewed .Tune 1.1928.

This invention relates to improvements in horizontal sliding windows, and particularly j moved when desired to adjust their setting,

is so arranged that the windows will be normally held against movement with equal eiiiciency regardless of the position oi the windows in their frames. and without any attention on the part ofv the operator being necessary to thus maintain them locked against movement. n

The holding means is also so arranged that both the top and bottom edges of the windows are clamped for their entire length, thereby eliminating vibration and rattles. At the same time the locking means is yieldable to a certain extent so that the windows can yield with any give of their frames, thus reducing the possibility of breakage ofthe windows to a minimum.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective tor the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following speciication and claims.

In the drawings similar characters of reference indicate corresponding parts in the severalviews:

' Fig. 1 is a side elevation of the'window structure partly broken out to show the yielding locking mechanism andlooking at the inner faces of the windows. v'

Fig. 2 is an enlarged transverse section on the line 2 2 of Fig. 1.

Referring now more particularly to the characters of reference on the drawings, the window frame comprises side members 1 (which extend below the windows to the frame of the car or to the bottom of the door if the windows are mounted in the latter), a top member 2 and a bottom member 3. The side members above the bottom member and the top member are provided with inwardly projecting and transversely grooved telt pads 4 to form guides and cushion means for the edges of transversely spaced window panes 5 which as is customboth windows are closed, as shown in Fig., l.

The bottom frame member 3 is provided `at its upper face with a longitudinal groove 3'al in which is positioned a rigid strip 6 preferably of metal. this strip a grooved `felt pad 7 is fixed, this pad being vertically alined with the upper pad 4 in opposed relation thereto to receive the lower edges ofthe panes. A plurality of longitudinally spaced bolts 8 is secured to and depend from thestrip 6 through en larged openings in the trame 3 and through guide plates 10 mounted over said openings on the lower face of thefframe.

Compression springs 11 disposed about the bolts bear at their upper ends against the strip 6 and at their lower ends against the plates 10. Thesesprings tend to force said strip upwardly and therefore clamp the panes 5 between the opposed pads 4 and 7 for their yfull length7 thereby equalizing the clamping pressure on the panes, and also preventing the same fromV vibrating and rattling. i

Below the frame 3 the bolts vare secured to the horizontal flange 12 of an angle plate 13 which lies adjacent one face of a vertical :trame structure 14 which projects below the frame 3 outwardly of the plane Vof the bolts 8 and is practically made as a part of said 'rame 3. The bolts are adjustable inthe flange so that the tension of thesprings can be altered at will. l

Secured to the inner face of the plate `centrally of the length thereofis a vertical and transverse bracket 15 onto which a lever 16 is pivoted intermediate its ends'. One end yof this lever projects through ,the plate 13 f and is pivoted onto a plate 17 mounted on On the upper face or-- ary overlap Aat their adjacent ends when thereto so that they can follow any weaving l or give or" the window frame. The springs being independent can yield as required by this movement of the plate. In this manner the placing of excessive strain on the panes with such give of the frame is avoided.

W'hen the pad 18 is depressed the plate 13 is lowered and the strip' 6 is of course lowered also so that the opposed horizontal Y edges of the panes are unclamped and may be slid freely along the guide pads. Upon releasing the lever the springs again exert '16 projecting through a vertical slot in said panel.

From the foregoing description it will be readily seen that I have produced such a device as substantially fuliills the objects of the invention as set forth herein.A

While this specification sets forth in de1 tail the present and preferredconstruction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

1. A sliding window holder comprising a frame structure to receive a pane for hori zontal sliding movement, guides for the horizontal edges of the pane, a rigid strip mounted in the frame extending lengthwise of and on which one of said guides is mounted, said strip being movable to and from the adjacent edge of the pane, yieldable means applied to the strip at different points in its length and acting automaticallyy and independently to force the strip toward the pane, and a control member applied to the strip for'movingthe same away from the pane.

2. A sliding window holder1 comprising a frame structure to receive a pane for hori- `zontal sliding movement, guides for the ed, said strip being movable to and from the adjacent edge of the pane, a plate mounted in vertical a inement with and in spaced relation to the strip, connection means between the strip and plate, springs between the frame and strip acting to -torce the latter toward the pane, and hand means applied to the'plate to move said plate and the strip against the pressure of the springs and away from the pane.

3. A sliding window holder comprising a frame structure to receive a pane for horizontal sliding movement, guides for the horizontal edges of the pane, a rigid strip` mounted Vinthe frame extending lengthwise of and on which one of said guides is mounted, said strip being movable to and from the adjacent edge ot' the. pane, a plate mounted in vertical alinement with and in spaced relation to the strip, longitudinally spaced bolts between the strip and plate, springs between the frame and strip'acting to force the latter toward the pane, and a handle ed in vertical alinementwith and in spaced relation to the strip, rigid connection means` Y Vbetween the plate and strip, compression springs at spaced intervals between the frame and strip, and means for moving the plate againstthe pressure olk the springs connected to the frame structure and to the plate centrally of its length.

5. A sliding window holder including a' frame structure to slidably receive a pane,

va guide for one longitudinal movable edge of the pane, yieldable means applied to the guide at different points in its length for `pressing the same against the said edge of the pane,.and control means applied to said guide for withdrawing the same from engagement with the edge of the pane.

In testimony whereof I ailix my signature.
